Abstract

The invention provides a dental implant of a composite structure and a manufacturing method of the same. By adopting effective structural design, different materials and different manufacturing modes, the dental implant is divided into a fastening screw, a screw thread implanting section, a multi-hole implanting section, a tentacle supporting structure and an implant main body which are integrated to form a composite structure, and the dental implant has good strength, good bone combining capability and good initial stability. The thread implanting section, the fastening screw and the implant main body form a main frame of a composite implant, thus strength of the whole implant is guaranteed; meanwhile, the composite structure can be used for overcoming the defects caused by a single manufacturing mode, and the respective advantages of structural design, the manufacturing modes and materials are fully realized; a tentacle supporting structure made from a degradable material has the effects of well inducing osteogenesis and enhancing initial stability of the implant whole and can be applied to immediate implantation; elasticity modulus of the implant overall material is optimized by virtue of a porous structure of the outer layer, combination of bone growth and guiding in initial stage can be facilitated, and initial stability with osseointegration is also improved by the combined expanded-type structure.

Description

technical field [0001] The invention relates to the field of oral implants, more specifically, to a dental implant with a composite structure and a manufacturing method thereof. Background technique [0002] At present, the dental implant system commonly used in the world is mostly a two-stage structure, which consists of three parts: dental implant, abutment and connecting screw. These product designs are formed on the premise of traditional machining manufacturing methods, and the structure is limited by machining equipment and technology. Generally, they are cylindrical, tapered or threaded, with relatively regular shapes and two-stage general sizes. A surface treatment for enhanced osseointegration is applied to the implant after machining. [0003] The current common surgical approach requires two surgical procedures to complete the entire repair. That is: the dental implant needs to be screwed into the drilled hole in the alveolar bone first, then the end of the impl...
